I have the denso irridiums and they are ok. Pretty much I change my plugs after everytime I go to the tracks. That is why I bought the denso because my friend said they handle better than the ngk after you race with them. It looks like after 3 times to the track i need to replace them-----My idle is a little rought now and I did replace my wires and cap and rotor so it is the plugs. Now that I think about it just regular ngk is good enough just got to change them. I do not think I will spend that kind of money on irridiums unless I got turbo or something. Just my opinion.
